Avaldatud<\/a><\/noindex> DNS-serveri BIND stabiilsete harude versioonide 9.11.18 ja 9.16.2 ning arenduses oleva eksperimenteeriva haru 9.17.1 parandusuuendused. Uutes v\u00e4ljaannetes on k\u00f5rvaldatud<\/a><\/noindex> turvalisuse probleem, mis on seotud r\u00fcnnakute kaitse ebat\u00f5hususega «DNS rebinding<\/a><\/noindex>» toimides DNS-serverina, mis suunab p\u00e4ringuid (seade «forwarders» seadistustes). Lisaks on tehtud t\u00f6\u00f6d, et v\u00e4hendada DNSSEC-i digitaalsete allkirjade statistika m\u00e4lu suurust - j\u00e4lgitavate v\u00f5tmete arv on iga tsooni kohta v\u00e4hendatud neljani, mis katab 99% juhtudest.<\/p>\n

DNS rebinding tehnika v\u00f5imaldab kasutaja avatud lehe kaudu veebibrauseris luua WebSocketi \u00fchenduse sisev\u00f5rgu teenusega, mis ei ole otse interneti kaudu kergesti ligip\u00e4\u00e4setav. Selleks, et m\u00f6\u00f6duda brauserites rakendatavast kaitsemehhanismist, mis takistab \u00fchenduse loomist praeguse domeeni piiridest v\u00e4ljapoole (cross-origin), muudetakse DNS-is hosti nime. R\u00fcndaja DNS-serveris konfigureeritakse j\u00e4rgnevalt kaht IP-aadressi edastamine: esimesele p\u00e4ringule antakse t\u00f5eline IP aadress, mis vastab lehele, ja j\u00e4rgnevatele p\u00e4ringutele antakse seadme siseaadress (n\u00e4iteks 192.168.10.1).<\/p>\n

Esimese vastuse eluaeg (TTL) seadistatakse miinimumv\u00e4\u00e4rtusesse, seet\u00f5ttu m\u00e4\u00e4rab brauser lehe avamisel r\u00fcndaja t\u00f5elise IP-aadresse ja laadib lehe sisu. Lehe peal k\u00e4ivitatakse JavaScripti kood, mis ootab TTL\u2019i l\u00f5ppemist ja saadab teise p\u00e4ringu, mis n\u00fc\u00fcd m\u00e4\u00e4rab hosti kui 192.168.10.1. See v\u00f5imaldab JavaScript\u2019il p\u00e4\u00e4seda ligi sisemises v\u00f5rgus olevale teenusele, \u00fcletades domeeni\u00fclese ehk cross-origin piiri. Kaitse<\/a><\/noindex> BIND-is sarnaste r\u00fcnnete t\u00f5kestamine p\u00f5hineb v\u00e4liste serverite IP-aadresside v\u00f5i lokaalsete domeenide CNAME aliaside tagastamise blokeerimisel, kasutades deny-answer-addresses ja deny-answer-aliases seadeid.<\/p>\n
